Problem with random reboots

I have a dual processor system (2 PII @ 450) with 256MB of RAM. I recently did a clean install of Windows 2000 and have installed all of the service packs and fixes. The problem is random reboots. It has been set not to automatically reboot in the event of a system failure and yet it does. It is not application specific. The BIOS has been recently updated. Case has three fans on the rear and one in the front. Both CPU's have fans. No clue as what to try next. Never had the problem when using Windows ME. Any help would be greatly appreciated.

I am assuming you don't have any messages in your Event Log about the cause of the restart. It just blows up and restarts, yes? No blue screen or Dr. Watson error before the crash?

When I get this symptom, I generally start looking at memory and I/O problems. Bad memory can certainly cause random reboots. So can a bad SCSI card or terminator. Do you use IDE or SCSI? You might have also uncovered a problem with the dual processors that would not have been apparent under ME. A bad power supply can also cause random reboots.

The first thing to do is reseat everything in the box. This baby is getting a little elderly, so blow out the dust bunnies. You might try taking out one of the processors to see if that resolves the problem. If not, swap in the other processor. Make sure you get the voltage regulators installed correctly.
